xAI maintains a persistent free Grok tier with access to core chat, limited real-time search, Grok Build, and connectors, but explicitly excludes Grok Bot—an agentic feature for persistent tasks, vendor integration, and autonomous workflows—from that plan. Recent August-September 2026 updates rolled Grok Bot to the $30 SuperGrok tier, Cursor plans, and enterprise offerings while introducing Grok 4.6/4.7 with stronger agent capabilities, reinforcing the paid positioning. A Bloomberg-reported October 2026 review of four-tier X/Grok subscriptions keeps the entry free level limited, with Grok Bot reserved for higher tiers like Ultra. Traders are watching for any policy shift ahead of potential subscription revamps or competitive responses from rivals expanding free agent access.
